MACHINE FOR MAKING GLASS BOTTLES.

SPECIFICATION forming part of -Letters Patent No. 700,191, dated May 20, 1902.

Application filed. July 13,1900.

T0 @ZZ whom, t nung concern: l Y Be it known that 4I, LUDWIG` GROTE, a subject of the Emperor of Germany, residing'at 84B East India Dock road, Poplar, ,Londo'n; England, have invented a new andvuseful Ilm-l provement in Machines for Making Glass Botties, of which the follow-ing is a specification. This invention relates to the manufacture of glass bottles by casting and blowing combined as practiced in part'by means of machinery in the manner set forth in my previous specifications, forming part of United States Letters Patent No. 628,313, datedthe 4th day of July, 1899, and Nos. 656,286 and 656,322, dated the 21st day of August, 1900.

The present inventionconsists in an improved glass-bottle machine that is constructed without many of the complications which have heretofore been considered necessary and thatis adapted to be rapidly and economically operated. Simplicity is of great importance in such machines, owin gto the high heat of the molten glass or metal for the product hereinafter termed the glass and-the necessity for using metallic molds and appurtenances which quickly absorb Yheat and are greatly affected byexpansion and con-. traction also, becausel it ,is desirable to avoid as much as possible delay for coolingthe machine in order that worlrmay proceedl as'rap-.f idly as practicable while the glass is lin blowing condition, and sofas to produce as many bottles as possible per hour.

The invention further consists in certain novel combinations of parts the nature and objects of which are hereinafter set forth.

Five sheets of drawings accompany this specification as part thereof.

Figure V1 of the drawings is a side elevation of the improved machine, illustrating the operation of casting the parison. Fig. 1X is a sectionall detail hereinafter described. Fig. 2 is 'a side elevation showing the parisonmold reversed. Fig`.j3 is a side elevation showing the parisonmold opened, exposing a depending parison and the finishing bodymold at the delivery-point opened, exposing a finishedV bottle for removal and in dotted lines'a body-mold closed varound saidl parison for the nishing operation. Fig. 4 is a front Serial No. 23,516. Y. (No model.)

' view with theparts as in Fig. 3, omitting the glass: Fig. 5 represents a substantially horizontal sect-ionen' the line a b, Fig. 3, and illustrates by dotted lines the release of a bottle by the'neck-mold. Fig. 6 represents a subs'tantially horizontal section on the line c d, Fig. 4.

Like letters and numbers refer to like parts in the several figures.

The improvedmachine comprises a pillar A, supported l'in upright position by a base B, which may be and preferably is circular in plan view and integral with the pillar, which may be an iron casting and either solid or hollow.

At or near the upper end of the pillar A a horizontal bore perpendicular to the front of the machine and preferably provided with bushingsl and 2 accommodates a tube C, to the rearend of which an air-pipe D is made fast by a coupling 3 and which is preferably adjustable lengthwise by means of a handwheel nut 4, swiveled to the bushing 1 and coacting with screw-threads 5 on the tube C.

In front of the pillar A a loose face-plate E is mounted on the tube C, together with the loose hub 6 of a combined plunger-support and air-conduit F and the interlaced loose knuckles? of the supporting-arms S of a bisect'ed parison-mold G,the escape of these parts from the pivotal end of the tube C being prevented by suitable means-as, for example, an axial screw 9.

To the face-plate E are hinged at 10 and 11, respectively, the halves of a bisected headmold or neck-mold II and a hand-lever I for actuating the mouth-forming and air-admitting plunger J, which is coupled thereto at 12 and is guided by the normally-vertical sleeve portion 13 of the plunger-support and air-conduit F. v l,

Suitable stops 14 and-.15 on'the pillar A and the face-plate E, respectively, arrest the faceplate and the parts that turn therewith'in the respective positions of rest in which they are shown in Fig. 1 and in Fig. 2, for example. The chamber of said sleeve portion 13 of the plunger-support and air-conduit F communicates with the interior of the tube C by Way of one arm 16 of the same, and this arm -is IOO provided with the housing or shell of an aircock K, by which the blowing operation is controlled.

The neck-mold II is provided with a pair of spring-detents 17, one in each of its halves, and the halves of the parison-mold G and of the finishing body-molds L and L2 are provided with counterparts 18 and 19, Fig. 1, to coact therewith for stopping the molds in alinement without positively interlocking the parts with each other. Such detents 17 may be, for example, of the known construction represented in Fig. 1X, where s represents a spiral spring sunk within a drilled socket in the end face of the neck-mold H,j` represents a follower seated on the spring s and having a conical point, the projection of which is limited, as by contracting the outer end of the socket, and 18 represents the detent counterpart in the end face of the parison-mold G in the form of a conical indentation, into which the detent 17 springs when the parts are alined, as in Fig. 1, and which is disengaged from the detent by such force as can readily be exerted by the hands of the operator. The plunger J is intended to be of the construction and mode of operation set forth in my previous specification forming part of said Letters Patent No. 656,286 and the cock K of the construction and mode of operation set forth in both of said previous specifications; but for the purposes of the present invention these parts and the several molds, apart from the features called for by the respective claims hereto appended, may be of any known or improved construction that is not inconsistent with the present combination and arrangement of molds and their appurtenances,broadly considered. The finishing-molds consist of said body-molds L and L2, which are open at both ends, and bottommolds M and M2 in combination with the neck-mold H. (See Fig. 3.)

The halves of each body-mold are hinged together and at the same time to a carrier N by a vertical hinge-bolt 20. The carrier is preferably and conveniently made in halves united by bolts 21, so as to facilitate applying it to the pillar A, around which it turns between shoulders 22 and 23, that determine the horizontal plane in which the carrier and the body-molds hinged thereto revolve. The upper ends of the body-molds are thus readily made to close snugly beneath the reversed neck-mold, as in dotted lines in Fig. 3, with the aid simply of suitable stops or alining detents 17, as above described.

The bottom-molds M and M2 are preferably and conveniently carried by one and the same support O, .turning around the pillar A, between collars 24 and 25. The bottom-molds are rendered vertically adjustable, as by screw-stems 26 and nuts 27, to insure tight joints between them and the lower ends of the body-molds; but when once adjusted for a given combination of molds they will ordi- 'naril y require no further attention. The bottom-molds M and M2 are also rendered adjustable toward and away from the axis of the pillar A in common with the neck-mold,

as by means of slots 28 to receive the screwf machine may be made without such adjustments and its simplicity of construction thus further increased.

Handles 29 to 40, inclusive, provide for manipulating the movable parts, and the handles 29, 31, and 35 are pivoted and operate the locking devices of the several molds in a known manner set forth in said previous specifications.

In operation the neck-mold I-I being closed and then the parisonfmold G the latter is by the same act clamped against the end face of the neck-mold that is provided with the detents 17 and the cavities of the two are alined with each other by said detents. Graspin'g the handles 30 and 32, the operator then inverts the parts that turn on the pivot-tubeC, so that they present the appearance represented in Fig. 1. The parison-mold G and. neck-mold H are then filled by an attendant with molten glass, as represented at X, Fig. 1, and the head of the bottle is cast within the neck-mold. Meanwhile the grasp of one hand has been transferred to the handle 33, and the lever I, and therewith the plunger J, is reciprocated. A single reciprocation forms the mouth of the bottle and leaves an initial cavity in the glass, into which air is at once gently admitted by manipulating the handle 34 of the air-cock K. With the cock-K partly open andthe plungerJ retracted the face-plate E and the parts tu rning therewith are reversed on the pivot-tube C by means of the handles 30 and 32 or 32 and 33, bringing said parts into the positions represented in Fig. 2. The parison-mold G is then unlocked by means of its handle 29, and by means of the same and the handle 30 the halves are separated and swung up into the elevated position in which they are shown in Figs. 3, 4, and 5. This exposes the glass with the same hanging from the neck-mold H, as shown at Y in Fig. 3, only at first irregular in shape. It is brought approximately to the form represented in Fig. 3 by working its lower end into a hemispherical shape, and thus rendering the bottom glass homogeneous and free from crevices and imperfections, or if bottles with deeplyindented bottoms (deep kickups) are to be produced it is worked and paddled inthe manner set forth in my previous specification forming part of Letters Patent No. 656,287, dated the 21st day of August, 1960. Meanwhile the gentle introduction of air is contin- IOO IIO

ned.` Finally, one of the finishing body-molds L or L2 is closed by means of its handles 35 36 or 37 38 around the depending glass, and the blowing of the bottle is completed by manipulating the handle 34 of the air-cock K. The neck-mold H is then opened on its hinge l0, as shown in dotted lines in Fig. 5, so as to release the head of the bottle. Meanwhile if a bottle has just beenblown in the other bodymold Lit has been standing in the mold at the delivery-point of the machine, as at Z in Figs.

1 and 2, and its mold is opened, asin Fig. 3

and the bottle is lifted by its head and carried oli by the time the operator is through i with the newly-blown bottle. The support O andthe pairs of body-molds and bottom-molds are then turned around the pillar A by means of one of the handles 39 4,0 to carry the newlyblown bottle into the delivery position Z and an empty and open body-mold L2 before the operator. He then, if he hasnot already done so, closes the empty neck-mold H andswings the halves of the parison-moldG into position beneath it, as in'Fig. 2, and then turns these parts into position, Fig. l, to receive a fresh charge of glass X, and thus the operation proceeds step by step without any unnecessary delay or interruption.

In practice the means foradj usting the machine for different sizes of bottles may pref-l erably be omitted in machines for large establishments, as already indicated. Ball-bearings may be provided at 22, 23, 24, and 25 to facilitate turning the inishing body-molds and bottom-molds around the pillar A, and other like modifications and mechanical-details will suggest themselves to those skilled in the art.
